Product Name: The ALL•AIR™ DH System
The ALL•AIR™ DH Whole Home Air Purification System is the most comprehensive and effective indoor air purifier available anywhere. Featuring L2B’s patented coating technology, it kills up to 99% of airborne pathogens such as viruses, bacteria and mould and destroys toxic volatile organic compounds (VOCs). The ALL•AIR™ DH Whole Home Air Purification System treats 100% of the air in your home on each air pass, making it a true whole home air purifier. The DH also utilizes three stages of air filtration to capture dust and other large particulate. These filters are exposed to a small amount of UV-C light that kills trapped contaminants and keeps you safe from bio-hazardous material during routine maintenance.

Product Name: The ALL•AIR™ DC In-Duct Module
The ALL•AIR™ DC In-Duct Module one of the most efficient and user-friendly commercial air purifiers available. It is designed for installation into any new or existing HVAC (Heating, Ventilation and Air Conditioning) air handler to prevent the risk of airborne pathogens from being distributed throughout a building. Multiple DC modules can be used in tandem to meet required UV dosages if necessary.

Our ALL•AIR™ DC In-Duct Modules can be configured to handle between 1,000 – 10,000 CFM while maintaining a kill rate of greater than 95%. The DC also breaks down volatile organic compounds (VOCs) using our patented high reflectance, photocatalytic oxidation coating technology.

Product Name: The ALL•AIR™ WR Portable System
The ALL•AIR™ WR Portable System utilizes three stages of air filtration to remove particulates, germicidal UV-C light to kill airborne microorganisms, and our patented, self-cleaning coating technology to breakdown toxic airborne chemicals. The WR also allows for a small amount of UV-C light to spill onto the filters, which kills trapped mould, viruses and bacteria. This eliminates the potential health risks associated with changing the contaminated filters. The WR is designed for floor, wall, ceiling or in-duct installations and is capable of treating 400-750 CFM.

Product Name: The ALL•AIR™ DR Rack Mount System
The ALL•AIR™ DR Rack Mount System sterilizes the cooling coil(s), an integral part of a building’s HVAC system. The coil(s) can host microorganisms, most commonly mold, which can contribute to respiratory illnesses and can easily trigger allergies. Uncontrolled, mold microbes can be distributed throughout the entire building by its HVAC system. UVGI of the HVAC cooling coil(s) prevents microbial buildup on the coil(s) and drip pan, inhibiting the release of pathogenic microorganisms. A clean cooling coil has a significant impact on the health and productivity of the building’s occupants.

Additionally, biological contamination buildup on the coil fins can affect thermal transfer through the coil and occasionally cause airflow blockage. A clean coil brings the building to temperature using less energy, reduces maintenance costs and ultimately results in operational cost savings.
